<acronym>, <h>, <big>, <center>, <u> and <noembed> are not in (X)HTML5.  
(<font> is only allowed for WYSIWYG tools, not for authors.)

The XML declaration and CDATA sections are not allowed in HTML5 (but they  
are allowed in XHTML5). Technically though they are allowed in HTML 3.2  
and HTML4, since the former is just a processing instruction in SGML and  
CDATA sections are also allowed in SGML (not that they are generally  
supported in HTML UAs though).

<tfooter> should be <tfoot>.

<wbr> isn't a soft hyphen, it's a "soft line break".

Framesets will not be in (X)HTML5 AFAIK.

According to the latest WD of XHTML2, the <h1> to <h6> elements are  
present:  
http://www.w3.org/TR/2006/WD-xhtml2-20060726/mod-structural.html#sec_8.5.

<xmp>, <listing> and <plaintext> are deprecated in HTML 3.2.

<label>, <fieldset>, <legend>, <optgroup>, <button> and <noscript> are not  
in HTML 3.2.


Nice work!
